Midwest is one of the principal sources of concrete and clay masonry units and related supplies in the central United States, with 15 production facilities, distribution yards and showrooms across its home state of Missouri, plus Arkansas, Illinois, Kentucky and Oklahoma. It has a full range of building and hardscape products for residential and com- mercial markets, and has been an early mover in technologies or building methods that dovetail block, brick and pavers, especially rainscreen enclo- sure systems, primarily in low- to mid-rise commercial buildings, and rain gardens designed to harvest rain and runoff in urban streetscapes. Midwest Block's market approach and skill in advancing the concrete masonry value proposition are embodied in the Fulton State Hospital, a $200 million-plus Missouri Department of Health facility nearing comple- tion. Project designers initially envisioned a precast concrete enclosure for 12 living areas. A Midwest Block-led coalition showed the architect and owner how concrete masonry units could improve on several aspects of the new complex; perform over a long life cycle; and, withstand severe weather exposure. "Missouri is prone to tornadoes and high winds," notes Midwest Block Vice President of Architectural Sales Manager Mark Wilhelms. "In this type of hospital there's no way they are going to move patients to a shelter in the event of a tornado. We ran different wall configurations through finite analysis and graphically showed how stresses were trans- ferred around windows and doors to the surrounding masonry, and how masonry walls and foundations could pick up those stresses and transfer them out through the wall. That went a long way to document that a masonry wall works as a system and not as individual pieces." The coalition prevailed, netting delivery of more than 1 million, primarily lightweight, concrete masonry units. The speed with which masons could lay the lighter weight block—abiding the project's fast track schedule goals—helped seal the decision for a concrete masonry enclosure over a precast alternative.
